ARTIFICIAL FINGER Russian patent published in 2018 - IPC A61F2/54 A61F2/58 A61F2/78 

FIELD: medicine.

SUBSTANCE: group of inventions relates to medicine. Artificial finger for prosthetics and gripping devices comprises a base pivotally mounted on the base of the first phalanx of the finger and at least one next phalanx hingedly mounted on the first phalange of the finger, as well as a drive for changing the position of the next phalanx relative to the first phalanx and the first phalanx relative to the base. At least one return element is provided for resetting the first phalanx and the next phalanx. First phalanx is loaded with a different return effort than the next phalanx. In the extensible phalanx of the finger and/or the next phalange, the point of switching of the force action between flexion and extension is located. Point of force exertion is made with the possibility of changing the position. Artificial finger comprises a base pivotally mounted on the base of the first phalanx of the finger and at least one next phalanx hingedly mounted on the first phalanx of the finger, and a drive for changing the position of the next phalanx relative to the first phalanx of the finger and the first phalanx of the finger relative to the base. On the base there are devices for osteointegrated fixation of the artificial finger, and a control device for the drive is provided which, based on electromyographic pulses or direct connection to the neural pathways, controls the drive.

EFFECT: invention provides a better fit of the artificial finger to the captured object.
